The great man has received quite a lot of criticism recently. The criticism is deserved juding by the piece reproduced below from the latest What's Brewing. Referring to Hartley's XB he says:
"If memory serves me well, I recall a darkish bitter with a strong malty character, quite different to the paler and hoppier bitter brewed by Jennings."
Now I never considered Hartleys XB to be darkish but that is a minor point. But Jennings' paler and hoppier? I think that maybe Mr Protz's memory may not be serving him as well as he thinks.
